以下を運営する予定です。電子私のUDOO Neo i.MX6開発ボードのアプリケーションUDOO Neo公式st1232 7インチタッチスクリーンキット。カスタムLinuxディストリビューションを作成しました。狭い（サムブランチ）「起動準備完了」イメージを構築する機能。すべてのXorgパッケージを保持するために「x11-base」イメージ機能を有効にしました。元のフリースケールハードウェアと完全に互換性のあるディストリビューションを持つパッチレイヤーを提供します。ただし、起動プロセスが終了すると、セグメント障害エラーメッセージが表示されますxinit。
これは私の/etc/X11/xorg.confファイルです：

私のXorg設定は正しいですか？ Xorgが正常に動作するために何が重要ですか？私はexport DISPLAY=:0それについてたくさん聞きましたが、それを実行しても私の問題は解決しません。
答え1
6.2はDRM用であり、imx6をサポートしていないため、vivante 5.0.11ドライバのバージョンをダウンロードする必要があります。参考資料を見ることができます。 https://lists.yoctoproject.org/g/meta-freescale/topic/68840298#24216 https://community.nxp.com/thread/526149
答え2
追加しました。今回のパッチ私のレイヤーに追加すると、これが機能します。
